Will the coupler on the end of a x738 54in deck driveshaft fit on the shaft of the hydraulic pump from a cat0 42 Hyd Tiller? In other words, is the diameter of the cat1 pump shaft the same diameter of the cat0 pump shaft? I read somewhere here a while ago that the conversion requires the driveshaft for the deck. My setup came with the auto connect and I didn't recieve a deck driveshaft, only the mid pto driveshaft. So I need to know if the hydraulic pump shafts are the same diameter, and if I buy the deck driveshaft that it will fit on the pump. I bought the cat1 mount bracket and the pump brackets for the conversion, but still can't get the hyd tiller pump connected to the tractor. Thank you for any and all help.
